Understanding Information Rights Management

New to Outlook 2003, Information Rights Management (IRM) enables you to secure a message, including any attachments, to prevent the recipient from printing, forwarding, or copying the message or attachment. The recipient can open the message only after she confirms her identity by logging on to her Passport account.

Although there are similarities between digital signatures and IRM, they're two distinct methods you can use to secure your messages. You can digitally sign and encrypt IRM-protected messages.

A digital signature is used to prove you are the person sending the message; encryption prevents someone who doesn't have your private key from opening the message.

IRM ensures the confidentiality of the message and attached documents by preventing the recipient from printing, forwarding, or copying a message that's sent with IRM enabled.
